Strange Aloe type plant near the Villa

In the small lane that leads down to our villa this Aloe type plant is just growing wild at the side of the road. We had never noticed a plant growing there but now it is flowering it is very noticeable, the flowers are opening up from the bottom a few more inches every day. To give a perspective the flowering part is about 6-8 foot long.

We suspect that a seed has been dropped by a bird and taken root. We have not seen one like this on our travels in Portugal or Spain so wonder if it has come from Morocco and the Sahara. If any one knows more about this mysterious plant please let me know.

The trees in the back ground, by the way, are Cork Oaks. The cork has been stripped off part way up the trunk. When the cork has been stripped the trunk underneath is dark orange but turns black after 6 months or so. The cork will grow back and be ready for stripping again after a minimum of 9 years.
